Which of these plants consist of a cymose inflorescence along with a syncarpous ovary?

Options

A. Onion
B. Potato
C. Soyabean
D. Both (A) and (B)

Answer

To solve the question of which plants consist of a cymose inflorescence along with a syncarpous ovary, we can follow these steps:

### Step 1: Understand the Terms
- **Cymose Inflorescence**: This type of inflorescence is characterized by having flowers that bloom from the apex of the flower axis. In cymose inflorescence, the main axis terminates in a flower, and lateral flowers develop below it.
- **Syncarpous Ovary**: This refers to an ovary formed from multiple carpels that are fused together. In a syncarpous ovary, the carpels of the gynoecium are united, forming a single compound ovary.

### Step 2: Analyze the Options
- **Option A: Onion**: Onions have a cymose inflorescence and a syncarpous ovary.
- **Option B: Potato**: Potatoes also exhibit a cymose inflorescence and have a syncarpous ovary.
- **Option C: Soybean**: Soybeans do not have a cymose inflorescence; they typically have a racemose inflorescence.
- **Option D: Both A and B**: This option suggests that both onion and potato fit the criteria.

### Step 3: Conclusion
Since both onion and potato exhibit cymose inflorescence and have syncarpous ovaries, the correct answer is:
- **Option D: Both A and B**.
